Benefits of Dolomite Lime and High Calcium Lime
The Benefits of Dolomite Lime. Dolomitic lime is added to the BOF process to increase soluble magnesium oxide in the bath, lowering the tendency of the steelmaking process to steal magnesium from refractories. The magnesium oxide found in dolomitic lime reduces the tendency of slag to dissolve the Magnesium oxide from the furnace refractory.
What Is Lime Used for in Water Treatment? | Sciencing
Lime is a manufactured product made from limestone (calcium carbonate) or dolomite (calcium magnesium carbonate ). The raw material is processed into quicklime and hydrated lime. Since it is alkaline, it's often used to adjust the pH of water and soils containing acidic components. It's used to treat both drinking water and wastewater.
